- [Instructor] One cannot
compare the running speed of the cheetah with other mammals, and they underlined other mammals. So let's think about what's going on here. They say, one cannot compare. Now, what are the things that they're saying one cannot compare? So they're saying the
running speed of the cheetah, that's one of the things they're saying that you cannot compare,
and then you're saying you cannot compare it with other mammals. So is this a reasonable
comparison right over here comparing the running speed of
something with other mammals? You're comparing a speed
with animals right over here, that doesn't make sense. Now it might be hard to
spot because you might say, okay, would I compare the
cheetah with other mammals? And that would make sense. If the sentence was, one cannot compare, if it just said the
cheetah with other mammals then this would make sense. You're comparing one
mammal to other mammals, so that would have been
a reasonable comparison, but that's not what's going on here. We're saying the running
speed of the cheetah with other mammals, so
really what the author, the person writing it is saying, one cannot compare the
running speed of the cheetah with the running speed of other mammals or with the speed of other mammals. With, so I would insert there the speed or the running speed of other mammals. You're comparing speed to speed. Now, which of these choices
have something like that? So I definitely wanna, I
definitely wanna change things. One cannot compare the
running speed of the cheetah with that of other mammals. Yeah, I mean, that seems reasonable. Instead of saying the
speed we could say that. So one cannot compare the
running speed of the cheetah with that of other mammals. So that being the speed of other mammals. So that, this one seems pretty good. One cannot compare the running
speed with any other mammals. Well no, here you're still comparing speed to mammals so that's strange. And then here you're still comparing speed to all other mammals, cannot
compare the running speed with all other mammals so
no, it doesn't make sense. You're comparing a speed to animals so definitely like that one.
